maybe you can upload the picture of the item here next time? because i visited your link today and there is no more info for this item on that page. it seems the item is already sold and removed from the website.

I would call it a separate game "Tetris DS (THQ)" since it was, as I read, independently developed of the Nintendo version (and in fact once the Nintendo version was announced, THQ questioned if Tetris Company had violated their license contract by granting Nintendo a license).

This is what CTR shows.

I'm not familiar with DS header stuff much, but could that "Nintendo" header data be data for the flash cart itself? (that "NTR-NTRJ" string is kind of suspicious as a sort of default data)

i have asked a seller about this game. he told me it is a pack with two separate games and not one cart with two games on it. maybe remove it from list when there are no informations that it is something else?

the only picture i have found is not very good, but it looks very thick (two boxes should fit into it above each other).
